SD schedule line
Schedule line category could not be determined
Sales-order processing cannot create a usable schedule line because schedule-line category determination fails.
Quick answer
- Most likely cause
- No determination entry exists for item category and MRP type.
- Check first
- Sales-order item category.
- First resolution step
- Confirm the material plant/MRP data and item category are correct.
Likely root causes
- No determination entry exists for item category and MRP type.
- Material MRP type is missing or unexpected.
- The item category/process is configured for a schedule-line behavior that does not match the material.
What to inspect
- Sales-order item category.
- Material MRP type in the plant.
- Schedule-line category determination customizing.
Resolution path
- Confirm the material plant/MRP data and item category are correct.
- Maintain the intended determination entry through SD configuration governance.
- Avoid assigning an arbitrary schedule-line category because it controls requirements, movement type and delivery relevance.
- Retest ATP and delivery creation.
